LV4900H-TLM-E

Audio Amplifiers Overview

The LV4900H-TLM-E is a Bi-CMOS LSI Class-D audio power amplifier manufactured by Sanyo Semicon Device. It features a bridge-tied load (BTL) output configuration delivering 10W per channel into an 8Ω load at a 12V supply voltage with 10% THD+N. The device incorporates unique feedback technology to achieve high audio quality without requiring external output LC filters. It operates with efficiency exceeding 85% and includes built-in protection circuits for overcurrent, thermal conditions, and low supply voltage.

Audio Amplifiers Feature Summary

• Supports circuit designs that do not require output LC filters
• High-efficiency class D amplifier system with low EMI
• Soft muting function reduces impulse noise at power on/off
• Full complement of built-in protection circuits

Audio Amplifiers Applications

• High quality flat display panel based systems
• Audio amplification in consumer electronics
• Compact audio equipment requiring filterless design

Audio Amplifiers Procurement Notes

Verify the manufacturer designation as Sanyo Semicon Device or its successor entities due to corporate restructuring history. Confirm the specific suffix -TLM-E corresponds to the required tape and reel packaging format if automated assembly is intended. Ensure compatibility with the HSOP-36 package dimensions during PCB layout verification.

Audio Amplifiers Selection Notes

Select this component for applications demanding high power output in a compact form factor without the volume penalty of passive output filters. Consider the BTL topology for improved signal-to-noise ratio and doubled voltage swing compared to single-ended configurations. Evaluate the thermal management requirements given the 10W continuous output capability and the specific efficiency characteristics under varying load conditions.

Audio Amplifiers Part Context

This part belongs to the LV4900 series of Class-D audio power amplifiers developed by Sanyo. It is designed as a stereo amplifier solution for modern display panels and portable audio devices where space constraints prohibit traditional linear amplifiers or complex filtering networks. The integration of boot strap diodes and headphone amplifiers further consolidates system functionality.
